Rheem GAS BOOSTED SOLAR WATER HEATER DRAINING THE WATER HEATER

DRAINING THE WATER HEATER

To drain the water heater:

Gas Booster Water Heater

• Turn off the water heater (refer to “To Turn Off The Water Heater” on page 50).

• Open a hot tap (preferably the shower outlet).

• Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on the

underside of the gas booster.

Water will drain from the gas booster.

• When water stops flowing from the gas booster, close the hot tap.

Note: It is recommended not to screw the drain plugs back in, until the water heater is to be turned on

again.

Solar Storage Tank

• Turn off the water heater (refer to “To Turn Off The Water Heater” on page 50).

• Close all hot water taps.

• Operate the relief valve release lever - do not let the lever snap back or you will damage the valve

seat.

Operating the lever will release the pressure in the water heater.

• Undo the union at the cold water inlet to the solar storage tank and attach a hose to the water

heater side of the union.

Let the other end of the hose go to a drain.

• Operate the relief valve again.

This will let air into the water heater and allow the water to drain through the hose.
